Hi,

Below are instructions to adjust brightness on HP laptop

1. • 
     Press the "Fn" key with the computer turned on and hold the key.
     
   • 
     Press the "F7" or "F8" key on some HP laptops, which are printed with a small sun icon on the key. The sun icon is filled on the function key for dimming the laptop. The other key is printed with a hollow sun icon for brightening the screen.
     
   • 
     Press the "Fn" and left arrow keys together on some HP laptops to turn down the brightness. The "Fn" and right arrow key will increase brightness. Press and release the right arrow key repeatedly, while holding down "Fn," to decrease the screen brightness slowly, or hold the keys to darken the screen as low as the setting will go.
     
2. 
   
3. For HP Monitors

Every laptop is different, so adjusting the brightness or contrast on your laptop may vary from the steps provided on this page. However, understanding the process of how to adjust the brightness or contrast will help you change your settings.
Most laptops adjust their brightness and other settings using the function key in conjunction with another key. For example, pressing and holding the function key (abbreviated as "Fn") and pressing the up or down arrow keys as shown in the picture below, increases and decreases the brightness.

Right click anywhere in the blank area of the screen then click on properties the following screen should come up
then click settings tab should then see a screen similar to this

Then look for your Graphic card properties for example after clicking Graphics Properties tab the following screen should give then the opportunity to change your settings


The above are some examples taken from my aspire desktop but should help you further resolving your problem with brightness

Hope this solves your problem

1. Press down the Fn key at the lower left end of your Compaq Presario keyboard. Keep the button held down and tap the F7 key to decrease the screen brightness by one step.

2. Tap the F7 key again with the Fn key still depressed to further decrease the brightness by one step. Continue hitting the F7 key until you reach the minimum LCD screen brightness.

3. Hold down the Fn key and tap the F8 key to increase the Presario's LCD screen brightness by one step. Keep pressing the F8 key until you reach the maximum brightness for your screen

HI

Check this

<Fn> + <→> Brightness up Increases the screen brightness.
<Fn> + <←> Brightness down Decreases the screen brightness.

if it is just the brightness you need turned down go into the battery settings and change the brightness there. hope this helps

<Fn> + <→> Brightness up Increases the screen brightness.

<Fn> + <←> Brightness down Decreases the screen brightness

If tese dont work either your LCD lamp or board may be going bad.

its because it has gone into power saving mode, you need to go into the power/battery settings and set the brightness at 100% and then choose that setting as default.
